Out Configuration Select (Input) - Used to set the PWM output configuration mode. See
Mode Configuration” on page
PWM Input (Input) - Inputs from a PWM modulator.
Reset Input (Input) - Reset inputs for channels 1/2 and 3/4 respectively. Active low.
VD Voltage Level Indicator (Input) - Identifies the voltage level attached to VD. When applying
5.0 V to VD, LVD must be connected to VD. When applying 2.5 V or 3.3 V to VD, LVD must be
GND.
Core Digital Power (Output) - Filter connection for the internally generated power supply for the
low voltage digital circuitry.
Digital Power (Input) - Low voltage power supply for internal logic.
Core Analog Power (Output) - Filter connection for internally generated power supply for the low
voltage analog circuitry
